Problems installing Linux Version

[Ababakar]

Hi there,

i just tried to install Calibre on a Ubuntu/Linux PC - but get an error when I want to download:

sudo -v && wget -nv -O- https://raw.githubusercontent.com/kovidgoyal/calibre/master/setup/linux-installer.py | sudo python -c "import sys; main=lambda:sys.stderr.write('Download failed\n'); exec(sys.stdin.read()); main()"

Leads to:

    raise err
socket.error: [Errno 101] Network is unreachable

I tried this in the last 3 days - because i thought the network/download page simply is down/unreachable.

But I still get the error.
Anyone got a hint or experienced the same problem?

That's a network issue. Check that you dont have a http proxy environment variable setup. And check that you can reach https://download.calibre-ebook.com using a browser. If you can, then you can always follow the manual download and install instructions on the download page.

I'm having exactly the same problem, and the ONLY application this is affecting is Calibre.

I have run full network troubleshooting on the whole system, and this seems to be a problem with the Calibre installer, and ONLY the Calibre installer.

Prior to this, the installer was also freezing up and throwing errors, saying that the PyQt4.qt module couldn't be found.

All of this began *immediately* after installing the latest update, 2.68, one day ago.

I have PyQt5.qt and pyQt4.qt both installed - there should be no conflict between them - and have gone backwards and tried deleting the full Calibre installation and re-installing from a clean system.

It was after i tried re-installing from a clean system that the installer started throwing the "network error" message.

ALL of these problems have emerged since the latest update. Nothing has changed on my system since attempting to update Calibre.

Since there were no changes whatsoever, to the installer or calibre's networking code in the previous release, that cannot be. Feel free to downgrade to the previous release if you dont want to listen to me. And your PyQt4 errors come from the bbcgf_ebook third party plugin you have installed in calibre, which does not have anything to do with the OP's issue. Kindly stick to posting in the bug report you already opened and dont confuse this thread with irrelevant information.

I don't know if you changed something - but now it works.

The only thing I did, was click on the download link you posted and started the linux64 download.

Just to give it a try I used the terminal again while the download went on: and this time the download started. Maybe a coincidence - anyway it looks like just a temporary thing (solution two is that i triggered something by opening the download link - but guess i am no expert on that).

Its up and working now. thank you.
